The “Friday Afternoon Mathematics Undergraduate Seminar” (FAMUS) is a weekly event consisting of announcements, talks, and faculty interviews. FAMUS takes place most Fridays at 3:00-4:00pm in Room 164 of the Adel Mathematics Building. Typically the first half of FAMUS consists of a talk on a mathematical topic while an interview of a faculty member takes place in the second half. FAMUS is hosted by Jeff Rushall.
Come join us for some entertaining talks! Refreshments always served.
Note that talks are listed in reverse chronological order.

Speakers: Gabby Stewart (NAU)
Abstract: Graph pebbling is a game played on graphs; most known results are associated with undirected graphs. Gabby has been investigating the following question in an undergrad research project: are there any directed graphs whose single vertex cover pebbling numbers are constant? If you want to know what all of this means, and if you want to see her new results, come to FAMUS on Friday! No prior knowledge of graph theory or graph pebbling is expected.
The faculty guest this week is Nellie Gopaul. [PDF of Flyer]
